Could you carefully solder a wire to the shell of a USB plug to use as a
bonding point?

Btdt:  use  SAL-MET flux after carefully filing/scraping a target bare spot
on the shell.  XACTO the boot carefully if needed to expose a target spot. 
SAL-MET works on every substance I've attempted, including stainless steel. 
I've kept the same bottle of the stuff around since the '60s when I bought
it.  Algalw.
